FastLineSeries issue in latest TeeChart Builds

[asupriya]

I have a weired issue with all new latest versions higher than 3.5.3225.32184

I have an array of fastline series that I fill in runtime. All my fastlines display properly with the 3.5.3225.32184 version. But, any latest versions of TeeChart displays point series for few charts in normal mode. However, when zoomed, they all correctly show a solid line.

I am uploading a powerpoint file that shows the issue. This issue is occurring rather consistantly with all new builds and because of this issue i am not able to use latest builds to take advantage of new features.

Please suggest a solution.

Thanks

Added later: I tried to upload the file at http://www.steema.net/upload/, but i got a server error that there is no space left on the device. I am emailing to support@steema.com

Hello asupriya,

I've tested it and it seems to work fine for me here. Please, could you send us a simple example project we can run "as-is" to reproduce the problem here?
You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page. Now, also if you want you can upload attachment in the post directly.

Please try the following code with 3.5.3225.32184 version and all above versions. You will see the issue.

The issue is with the myFastLine.DrawAllPoints = False. If you set to true, all is good. But, my data is so big that I can't afford to set it to true.

Code: Select all

Public Class Form1
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim myChart As New Steema.TeeChart.TChart

        myChart.Dock = DockStyle.Fill
        Me.Controls.Add(myChart)
        Dim myFastLine As New Steema.TeeChart.Styles.FastLine(myChart.Chart)
        myFastLine.DrawAllPoints = False
        Dim selector1 As New Steema.TeeChart.Tools.Selector(myChart.Chart)
        selector1.AllowResizeChart = True
        myChart.Legend.Visible = False
        myFastLine.FillSampleValues(1800)
    End Sub
End Class
